This is an image of Tourmaline, photographed from two different angles with polarised light.
Tourmaline is Pleochromic, meaning it changes colour as the angle changes. This isn’t a surface effect like the changing rainbow colours on an oil slick, it happens throughout the crystal.
The crystal structure in Tourmaline is anisotropic, which means it looks different from different directions. That means light coming in from different directions experience different effects and can get absorbed in different amounts, leading to something very cool.
It also happens with other crystals, like this Cordierite


There needs to be a video of this!

Here’s a gif. I like gifs. This is Iolite, the gem version of Cordierite, changing colour as the angle changes. Pretty. If you absolutely need a video though, here’s the source

The Beautiful Rings of Saturn

The Saturn system reveals tantalizing vistas. NASA’s robotic spacecraft named Cassini carries with it 12 instruments designed to take precise measurements of Saturn and its surroundings, including Titan, other icy moons, and the rings, as well as the magnetic environment.
For many of us, however, the images are what put us there, at Saturn, almost a billion miles away from home. Some of those images unveil overwhelming beauty. Others show tricks of light and seemingly magical oddities. Some reveal events from the distant past that have been preserved for eons, while other views depict processes that are changing now, like live news.

Filaments on the Inner Ring of the Helix Nebula

This cropped version of the Helix Nebula (also known as NGC 7293) mosaic shows cometary-filaments embedded along a portion of the inner rim of the nebula’s red and blue gas ring. The Nebula is in the constellation Aquarius at a distance of 650 light-years from Earth. The Helix is one of the nearest planetary nebulae to Earth and it a frequency target of study. Because of its ere stare it is sometimes called the “Eye of God”.

Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northernconstellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes are highlighted in thiscolorful skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The atomic emission is powered by energetic radiation from the hot stars, whose powerful winds and radiation also sculpt and erode the denser pillar shapes.

"Filbert Weevil" (Curculio occidentis)
…a species of ‘acorn weevil’ (Curculio spp.) which is recorded occurring in California and surrounding areas. Filbert weevil larvae are noted for feeding on a variety of oak tree species. This has caused them to be regarded as a major pest due to the damage they cause to acorns.
